At the beginning of the COVID-19 pandemic, the world was unprepared for such a massive challenge to global health. Individual testing kits and personal protective equipment were scarce. There were minimal ways to track the rapid spread of the disease, until researchers discovered that SARS-CoV-2, the virus that causes COVID-19,...
Soil solarization is a pre-planting practice to reduce weed pressure by trapping solar energy using a transparent polyethylene film to heat soil. Soil solarization has been successfully used in regions with high solar radiation. The purpose of this research was to determine if soil solarization under Pacific Northwest conditions could...
The nature of the bioluminescence of Gonyaulax catenella is
similar to that observed for other dinoflagellates in culture, showing
photoperiod-entrained rhythms of luminescence and stimulability
with relatively constant luminescent capacity during scotophase. G.
catenella is very sensitive to stimulation and photoinbibition. The
nature of the response to stimulation by bubbling...
This thesis examines the impact of urban renewal on individual health, specifically focusing on an urban planning model called Smart Growth that is being used in Portland, Oregon. Findings are based on qualitative and quantitative analyses of interview and survey data from study participants living in a community where renewal...
Coho salmon (Oncorhynchus kisutch) migration and spawning are unique components of the salmon life cycle because they require synchrony of behavior with other individuals as well as with acceptable fluvial conditions. As with other organisms that exhibit group mating behavior, it is likely that environmental cues trigger coho salmon movement...
The bacterium most frequently used in microbial
leaching processes and studies is Thiobacillus
ferrooxidans. Applications of this bacterium include the
treatment of coal, low-grade ores and industrial solid
wastes for the solubilization of pyrite and other trace
metals associated with sulfides. The goal of this study
was the development of...
In 2008, the Oregon State TRIGA® Reactor (OSTR) was converted from highly-enriched uranium (HEU) fuel lifetime improvement plan (FLIP) fuel to low-enriched uranium (LEU) fuel. This effort was driven and supported by the Department of Energy's (DoE's) Reduced Enrichment for Research and Test Reactors (RERTR) program. The basis behind the...
This research examines the impact of low health literacy among patients with End Stage Renal Disease. The sample included individuals who participated in a health education class (Pre-Renal Education Program) offered at the Samaritan Dialysis Services in Corvallis, Oregon. Data collection techniques included participant observation, individual interviews, evaluation of the...
CisCis-Dichloroethylene (ciscis-DCE), 1,1,1-Trichloroethane (1,1,1-TCA), and 1,4-Dioxane (1,4-D) are chlorinated solvents used as solvents and degreasers in industrial cleaning agents that have become common groundwater contaminants. To develop an effective treatment method for these compounds, polyvinyl alcohol (PVA) and sodium alginate (SA) hydrogel beads were co-entrappcapsulated with Rhodococcus rhodochrous Strain ATCC...
